[0063] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in combination with the drawings.

[0064] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other in the case of no conflict. The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0065] The present disclosure provides a floor assembly, Figure 1 is a schematic view of the overall structure of the floor assembly from one perspective, Figure 2 is a schematic view of the overall structure of the floor assembly from another perspective, in combination with Figure 1 , Figure 2 As shown in the drawings, the floor assembly comprises a middle channel structure 1, a floor body 2, a cross beam assembly 3 and a longitudinal beam assembly 4. The floor body 2 is fixedly connected to one side of the middle channel structure 1. The cross beam assembly 3 comprises first and second cross beams 31 and 32 which are parallel to each other, and the first cross beam 31 is fixedly connected to the upper surface of the floor body 2 and the middle channel structure 1, respectively.

[0066] Among them, Figure 3 is a sectional view of the floor assembly at the first cross beam 31, Figure 4 is a sectional view of the floor assembly at the second cross beam 32. In combination with Figure 3 , Figure 4 As shown in the drawings, a first cavity A is formed between the lower surface of the first cross beam 31 and the floor body 2, the second cross beam 32 is fixedly connected to the upper surface of the floor body 2 and the middle channel structure 1, respectively, and a second cavity B is formed between the lower surface of the second cross beam 32 and the floor body 2. In combination with Figures 2 to 4 As shown in the drawings, the longitudinal beam assembly 4 comprises first and second longitudinal beams 41 and 42, the first longitudinal beam 41 is fixedly connected to the lower surface of the floor body 2, a third cavity C is formed between the upper surface of the first longitudinal beam 41 and the floor body 2, the second longitudinal beam 42 is located on the side of the first longitudinal beam 41 close to the middle channel structure 1, and is fixedly connected to the floor body 2 and the middle channel structure 1, respectively, and a fourth cavity D is formed between the upper surface of the second longitudinal beam 42 and the floor body 2 and the middle channel structure 1.

[0067] In the present disclosure, through the cross beam assembly 3, the first cavity A and the second cavity B can be formed on the side of the upper surface of the floor body 2, so that the impact force of the vehicle body in the extension direction of the cross beam assembly 3 can be absorbed by the cavities. At the same time, through the longitudinal beam assembly 4, the third cavity C and the fourth cavity D can be formed on the side of the lower surface of the floor body 2, so that the impact force of the vehicle body in the extension direction of the longitudinal beam assembly 4 can be absorbed by the cavities. Thus, the collision in different directions can be buffered by multiple cavities, so that the anti-intrusion deformation capability of the vehicle body can be greatly improved, and the collision safety performance of the vehicle can be greatly improved.

[0068] As Figure 1As shown, the first cross beam 31 and the second cross beam 32 are fixedly connected with different parts of the floor body 2 respectively, so as to buffer the lateral impact on the vehicle at different parts. In this way, the collision safety performance of the vehicle in the lateral direction can be further improved.

[0069] Similarly, as shown, Figure 2 the first longitudinal beam 41 and the second longitudinal beam 42 are fixedly connected with different parts of the floor body 2 respectively, so as to buffer the longitudinal impact on the vehicle at different parts. In this way, the collision safety performance of the vehicle in the longitudinal direction can be further improved.

[0070] As shown in combination with Figure 1 , Figure 2 , it can be seen that the floor assembly is a symmetrical structure. The floor assembly includes two floor bodies 2, which are located on both sides of the center channel structure 1 respectively and are mirror-symmetrically arranged, and are fixedly connected with the center channel structure 1 respectively. Correspondingly, the cross beam assembly 3 includes two first cross beams 31 and two second cross beams 32 which are mirror-symmetrically arranged, and the longitudinal beam assembly 4 includes two first longitudinal beams 41 and two second longitudinal beams 42 which are mirror-symmetrically arranged. In this way, the two first cross beams 31 can buffer the lateral impact force on the vehicle on both sides of the center channel structure 1 respectively, and the two first longitudinal beams 41 can buffer the longitudinal impact force on the vehicle on both sides of the center channel structure 1 respectively, so as to greatly improve the anti-collision ability of the vehicle.

[0071] In some embodiments, as shown in Figure 1 , the floor assembly further includes a bracket assembly 5. The bracket assembly 5 includes a first bracket 51, which is located at one end of the first cross beam 31 close to the center channel structure 1, and is fixedly connected with the first cross beam 31, the floor body 2 and the center channel structure 1 respectively, as shown in Figure 3 The lower surface of the first bracket 51 and the first cross beam 31 form a fifth cavity E.

[0072] In this way, the fifth cavity E can be formed above the first cross beam 31 by the first bracket 51, and the fifth cavity E and the first cavity A are adjacent in the up-down direction, so as to improve the anti-deformation ability of the one end of the first cross beam 31 close to the center channel structure 1 in the up-down direction, and further improve the anti-collision ability of the vehicle.

[0073] In some embodiments, as shown in Figure 1 , the longitudinal beam assembly 4 further includes a rocker longitudinal beam 43 fixedly connected with the floor body 2. The bracket assembly 5 further includes a second bracket 52, which is located at one end of the first cross beam 31 away from the center channel structure 1, and is connected with the first cross beam 31, the floor body 2 and the rocker longitudinal beam 43 respectively, as shown in Figure 3As shown, a sixth cavity F is formed between the lower surface of the second support 52 and the first crossbeam 31.

[0074] Thus, through the second bracket 52, a sixth cavity F can be formed above the first crossbeam 31. The sixth cavity F and the second cavity B are adjacent in the vertical direction, thereby improving the deformation resistance of the end of the first crossbeam 31 near the central channel structure 1 in the vertical direction, so as to further improve the vehicle's anti-collision capability.

[0075] Optionally, the first bracket 51 and the second bracket 52 are used to install the seats. Since the seats in the vehicle are mounted on the floor structure, the floor structure needs to withstand a significant load at the seat mounting location. Supporting the seats with the first bracket 51 and the second bracket 52 prevents deformation of the floor structure at the seat mounting location, thereby further improving the structural strength of the vehicle.

[0076] Corresponding to the two first crossbeams 31, the support assembly 5 includes two first supports 51 and two second supports 52. The specific connection relationship will not be described here.

[0077] In some embodiments, combined with Figure 1 , Figure 3 As shown, the central channel structure 1 includes a main body 11 and a first reinforcing plate 12. The main body 11 has a frame structure with an open bottom. The first reinforcing plate 12 is located on the upper part of the main body 11 and is fixedly connected to the main body 11. Its lower surface is spaced apart from the main body 11 to form a seventh cavity G.

[0078] Thus, by forming a seventh cavity G on the top of the main body 11 through the first reinforcing plate 12, the deformation resistance of the main body 11 in the vertical direction is improved, and the deformation resistance of the central channel structure 1 in the extension direction is also improved. Therefore, this disclosure, through the cooperation of the main body 11 and the first reinforcing plate 12, can further improve the vehicle's collision avoidance capability.

[0079] like Figure 3 As shown, the main body 11 has a hollow channel inside. This enhances the torsional and bending stiffness of the vehicle body, thereby improving the overall rigidity of the vehicle.

[0080] In some embodiments, such as Figure 2 As shown, the central channel structure 1 also includes a second reinforcing plate 13, combined with... Figure 3 As shown, the second reinforcing plate 13 is located inside the main body 11 and is fixedly connected to the two inner sidewalls of the main body 11, and the upper surface forms an eighth cavity H between the main body 11 and the upper surface.

[0081] In this way, the sidewalls of the frame-structured main body 11 can be supported by the second reinforcing plate 13, thereby improving the structural strength and overall rigidity of the main body 11. Furthermore, the upper surface of the second reinforcing plate 13 forms an eighth cavity H with the main body 11, which can further improve the deformation resistance of the main body 11, thereby improving the overall deformation resistance of the central channel structure 1 and enhancing its anti-collision performance.

[0082] In some embodiments, such as Figure 1 As shown, the central channel structure 1 also includes a connecting plate 14, which is fixedly connected to the main body 11 and the first reinforcing plate 12 respectively, and protrudes from the side of the floor body 2. The connecting plate 14 is raised relative to the first reinforcing plate 12 to connect with the vehicle body. The connecting plate 14 has an opening groove 141 to form a reinforcing groove with the vehicle body.

[0083] Thus, the connecting plate 14 enables the connection between the main body 11 and the vehicle body. Compared to a one-piece molded structure, this design improves production efficiency and reduces waste. Furthermore, the split design prevents deformation during production caused by an excessively long central tunnel structure 1, thereby increasing the yield rate of the central tunnel structure 1. In addition, the connecting plate 14 has an opening groove 141 and forms a ninth cavity with the vehicle body, further enhancing the deformation resistance of the central tunnel structure 1.

[0084] In some embodiments, such as Figure 1 As shown, the central channel structure 1 also includes a third reinforcing plate 15. Figure 5 This is a sectional view of the central channel structure 1 taken along the extension direction of the central channel structure 1 at the connecting plate 14 and the third reinforcing plate 15, combined with... Figure 5 As shown, the third reinforcing plate 15 is located on the upper part of the connecting plate 14 and is fixedly connected to the connecting plate 14, and its lower surface forms the tenth cavity J with the connecting plate 14.

[0085] Thus, by forming the tenth cavity J through the third reinforcing plate 15 and the connecting plate 14, the structural strength of the central channel structure 1 at the connecting plate 14 can be strengthened, thereby improving the anti-deformation capability of the central channel structure 1 at the connecting plate 14. This can buffer the external impact force when the vehicle body is involved in a collision, thereby improving the vehicle's anti-collision performance.

[0086] In some embodiments, such as Figure 1 As shown, the longitudinal beam assembly 4 also includes a cover plate 44, a portion of which is connected to the upper surface of the floor body 2, and another portion of which is raised relative to the floor body 2. The raised portion of the cover plate 44 is used to connect to the vehicle body.

[0087] Thus, the connection strength between the floor assembly and the vehicle body can be improved by the cover plate 44, thereby improving the overall structural strength of the vehicle.

[0088] Optionally, such as Figure 1 As shown, part of the cover plate 44 is fixedly connected to the second crossbeam 32.

[0089] In some embodiments, such as Figure 1 As shown, the floor body 2 has multiple protrusions 21 and multiple grooves 22.

[0090] This improves the structural rigidity of the floor body 2, thereby increasing the overall rigidity of the vehicle and enhancing its collision avoidance performance, thus improving the vehicle's safety performance.

[0091] The floor assembly provided in the embodiments of this disclosure will be further described below with reference to some accompanying drawings.

[0092] Figure 6 This is a structural schematic diagram of the floor body 2, as shown below. Figure 6 As shown, the floor body 2 includes multiple protrusions 21 and grooves 22 to enhance the floor's resistance to deformation. The floor body 2 has a first protrusion 2a and a second protrusion 2b. The first protrusion 2a is located at the bottom of the first crossbeam 31 and is adapted to fit the first crossbeam 31. The second protrusion 2b is located at the bottom of the second crossbeam 32 and is adapted to fit the second crossbeam 32. Thus, the first crossbeam 31 and the second crossbeam 32 can be positioned for installation using the first protrusion 2a and the second protrusion 2b, thereby greatly reducing the difficulty of assembling the first crossbeam 31 and the second crossbeam 32. The edge of the floor body 2 also has a snap-fit ​​notch 2c for positioning the central channel structure 1 and the second longitudinal beam 42.

[0093] The floor body 2 has a thin-plate planar structure, and the material is selected from metal or polymer materials, such as cold-rolled thin steel sheet. The thickness of the material can be 0.5mm-2mm, which is determined according to the strength of the material.

[0094] Figures 7 to 12 Schematic diagrams of each component in the central channel structure 1 are shown.

[0095] Figure 7 This is a structural schematic diagram of the main body 11, as shown below. Figure 7As shown, the main body 11 includes a first main body portion 111, a second main body portion 112, a third main body portion 113, and a fourth main body portion 114 connected in sequence, wherein the height of the main body portion 11 increases progressively from the first main body portion 111 to the fourth main body portion 114. The first main body portion 11 has a first slot 11c on its side for engaging the end of the first crossbeam 31, and the third main body portion 11 has a second slot 11d on its side for engaging the end of the second crossbeam 32. This slot-based connection method facilitates the installation and positioning of the first and second crossbeams 31 and 32, thereby improving the ease of floor assembly assembly.

[0096] The edges of the first main body portion 111, the second main body portion 112, the third main body portion 113, and the fourth main body portion 114 extend outward to form a first connecting portion 11a. The first connecting portion 11a connects to the first crossbeam 31, the second crossbeam 32, and the floor body 2. The first connecting portion 11a has multiple concave and convex structures, which serve two purposes: firstly, to position the first crossbeam 31, the second crossbeam 32, and the floor body 2 for installation with the main body portion; and secondly, to improve the deformation resistance of the first connecting portion 11a.

[0097] Optionally, the first connecting part 11a can be connected to the first crossbeam 31, the second crossbeam 32 and the floor body 2 by means of, but not limited to, spot welding, CO2 welding, riveting, bolting, bonding or SPR (Self-Piercing Riveting).

[0098] The top of the fourth main body 114 has a second connecting part 11b, which has multiple strip-shaped grooves for positioning and connecting the first reinforcing plate 12 to improve the convenience of floor assembly assembly.

[0099] Optionally, the second connection 11b can be connected to the first crossbeam 31, the second crossbeam 32, and the floor body 2 by means of, but not limited to, spot welding, CO2 welding, riveting, bolting, bonding, or SPR.

[0100] The central channel structure 1 is a thin-plate planar structure, made of metal or polymer materials, such as cold-rolled thin steel sheet. The thickness of the material can be 0.5mm-2mm, depending on the strength of the material.

[0101] Figure 8 This is a structural schematic diagram of the first reinforcing plate 12, as shown below. Figure 8As shown, the first reinforcing plate 12 has an M-shaped structure, including a first reinforcing portion 121, a second reinforcing portion 122, a third reinforcing portion 123, and a fourth reinforcing portion 124. The first reinforcing portion 121 is used to structurally reinforce the first main body portion 111, the second reinforcing portion 122 is used to structurally reinforce the second main body portion 112, the third reinforcing portion 123 is used to structurally reinforce the third main body portion 113, and the fourth reinforcing portion 124 is used to structurally reinforce the fourth main body portion 114. This improves the deformation resistance of the central tunnel structure 1, thereby enhancing the vehicle's safety performance.

[0102] Optionally, the first reinforcing plate 12 has a thin planar structure, and the material is selected from metal or polymer materials, such as cold-rolled thin steel sheet. The thickness of the material can be 0.5mm-2mm, which is determined according to the strength of the material. The first reinforcing plate 12 can be connected to the main body 11 by means of, but not limited to, spot welding, CO2 welding, riveting, bolting, bonding or SPR.

[0103] Figure 9 , Figure 10 This is a structural schematic diagram of the second reinforcing plate 13, in which... Figure 9 This is a structural schematic diagram of the first inner plate 131, which is located below the third main body 11. Figure 10 This is a structural schematic diagram of the second inner plate 132. The second inner plate 132 is located below the first main body 11. The first inner plate 131 and the second inner plate 132 can be connected to the main body 11 by means of, but not limited to, spot welding, CO2 welding, riveting, bolting, bonding or SPR.

[0104] The sidewalls of the first inner plate 131 and the second inner plate 132 are fixedly connected to the main body 11 to form the eighth cavity H, thereby enhancing the structural strength of the central channel structure 1 and improving its resistance to deformation, thus improving the vehicle's safety performance. Furthermore, the first inner plate 131 and the second inner plate 132 reinforce the main body 11 at different locations, further ensuring that the main body 11 has high structural strength at all locations.

[0105] Figure 11 This is a structural schematic diagram of the connecting plate 14, which has a third connecting portion 14a and a fourth connecting portion 14b. The third connecting portion 14a is located at the top of the connecting plate 14, and its upper surface has multiple strip-shaped protrusions 21 to engage with the strip-shaped grooves on the second connecting portion 11b, thereby enabling the positioning of the connecting plate 14, reducing the assembly difficulty of the central channel structure 1, and improving the assembly efficiency of the central channel structure 1. The fourth connecting portion 14b is located at the lower edge of the connecting plate 14 and is used to connect to the vehicle body.

[0106] The connecting plate 14 has a thin, planar structure and is made of metal or polymer materials, such as cold-rolled thin steel sheet. The thickness of the material can be 0.5mm-2mm. The connecting plate 14 can be connected to the main body 11 by means of, but not limited to, spot welding, CO2 welding, riveting, bolting, bonding, or SPR.

[0128] Combination Figure 1 and Figure 2 In summary, the floor assembly provided in this embodiment achieves a longitudinally enclosed cavity structure between the left sill beam 43 and the vehicle body, a longitudinally enclosed cavity structure between the left cover plate 44 and the left first longitudinal beam 41, a longitudinally enclosed cavity structure between the central channel structure 1 and the left second longitudinal beam 42, a longitudinally enclosed cavity structure between the connecting plate 14, the first reinforcing plate 12, the third reinforcing plate 15 and the main body 11, a longitudinally enclosed cavity structure between the central channel structure 1 and the right second longitudinal beam 42, a longitudinally enclosed cavity structure between the right cover plate 44 and the right first longitudinal beam 41, and a longitudinally enclosed cavity structure between the right sill beam 43 and the right side of the vehicle body. This structure achieves seven longitudinally enclosed cavity structures, greatly enhancing the impact force transmission capacity of the longitudinal beams in a frontal collision and significantly improving the vehicle body's resistance to intrusion deformation. The seven longitudinally enclosed cavity structures greatly enhance the longitudinal strength and stiffness of the floor assembly.

[0129] In the design structure of this floor assembly, the left first crossbeam 31, the first inner panel 131, and the right first crossbeam 31 are designed as a single horizontal line, forming a transversely enclosed cavity structure with the left sill longitudinal beam 43, the left floor body 2, the main body 11, the right floor body 2, and the right sill longitudinal beam 43.

This structure connects the left and right sides of the vehicle body with two transversely enclosed cavities, significantly enhancing the lateral impact force transmission capability of the floor assembly during side collisions and greatly improving the vehicle's resistance to intrusion deformation. The two transversely enclosed cavities significantly improve the lateral strength and rigidity of the floor assembly.

[0131] In this embodiment, the wheelbase of the vehicle can be lengthened or shortened by longitudinally lengthening or shortening the left floor body 2, the central channel structure 1, the right floor body 2, and the left and right side sill longitudinal beams 43. The width of the vehicle can be widened or narrowed by adjusting the depth of the left and right sill longitudinal beams 43, maximizing the versatility of this floor assembly.
